CEO Sundar Pichai has announced that the firm has completely wiped out its carbon footprint by investing in "high-quality carbon offsets".
The company declared themselves carbon-neutral in 2007, and 13 years later they've now met another goal as part of their actions to help fight climate change.
What's more, Google has vowed to make all of their data centres and offices carbon-free by 2030.
Pichai said: "In our founding decade, Google became the first major company to be carbon neutral. In our second decade, we were the first company to achieve 100% renewable energy. By 2030, we aim to be the first major company to operate carbon free."
But he addmitted: "Moving towards carbon free by 2030 won't be easy."
The executive insisted it's the "biggest sustainability moonshot yet" to become carbon-free.
He said: "We'll do things like pairing wind and solar power sources together and increasing our use of battery storage.
"And we're working on ways to apply AI [artificial intelligence] to optimise our electricity demand and forecasting."
Environmental charity Greenpeace has hailed Google for setting "a new high-bar for the sector" with their goals.
Elizabeth Jardim, senior corporate campaigner at Greenpeace USA, commented: "Today's announcement, combined with Google's promise in May to no longer create artificial intelligence solutions for upstream oil and gas exploration, shows that Google takes its role in combating climate change seriously."
